DRAFT-EQUALIZ ER.

SPECIFICATION forming part of Letters Patent No. 253,056, dated January 31, 1882.

Application filed June 29, 1881. Model) To all whom it may concern:

Be it known that I, FRANKLIN B. HUNT, of Richmond, in the county of Wayne and State of Indiana, have invented certain Improvements in Combined Double-Tree and Evener, of which the following is a specification.

My invention relates toa newand improved double-tree and evener combined for sulkyplows and other uses, as hereinafter fully set forth and described in the specification and claims.

Figure 1 is a plan or top "iew of the combined double-tree andevener. Fig. 2 is afront plan of the double-tree strips and the central iron to which the draft is attached. Fig. 3 is a side elevation of same. Fig. 4 represents the middle single-tree with the loop to which the inner ends of the eveners are attached. Fig. 5 represents the loop which attaches to the plow-beam and the center of the doubletree strips. Fig. 6 represents one of the eveners with the single-tree attached thereto.

A A are the double-tree strips, and B B the eveners placed between them and held in place by means of the loops or bands J J passing around the double-tree strips and eveners. These bands are held in place on the doubletree strips by means of the wood-screws J J passing into the edge of the strips. The woodscrews M M also pass through these loops or hands and into the eveners in front to hold them in position. The loops L Lpass around the outer ends of the eveners and the middle of the sin gle-trees O E, and are held onto the eveners by means of wood-screws L L in rear, and onto the middle of the single trees by means of wood-screws N N. The loop K, Fig. 4, passes around the middle sin gle-tree, D, and the ends K pass backward through the openings P of the plate H, which plate is attached to the center of the double-tree strips by means of bolts or wood-screws I I. The hooks on the inner ends of the eveners, as shown in Fig. 6, are hooked into the holes in the ends K of loop K; hence the play of the eveners may be adjusted to suit circumstances by hooking in different holes. If either outside horse should start suddenly, the loop K is drawn back against the central projection of plate H but if the middle horse should start suddenly he pulls the inner ends of the eveners forward until theystrike against the outer ends of plate H and are stopped. Thus it will be seen that there is a limit to the movement both ways, and it may be adjusted to play different distances, according to circumstances, simply by placing the hooks on the ends of the eveners in different holes in the ends K. The vertical hole S in the center of plate H receives the bolt T through the ends of clip or loop G. The plate H has a tongue, V, extending backward from its center, as seen in dotted lines inFig. 3. This tongue supports and keeps the double-tree strips from being pressed inward, while the clip Gr supports and prevents their being pressed outward; hence there is a straight pull edgewise of the timbers, which are all placed arch side fore-most, and all the parts held in position by means of small woodscrews entering the timber laterally, there being no vertical bolt through the timber to weaken it in anyway. The ends of the eveners are rounded in the rear, where the clips L pass over them, to allow full play, as seen at 0, Fig. 6.

The traces are attached to the single-trees by means of short hooks and-springs, as seen in Fig. 1. These short hooks, in conjunction with the timbers placed arch side foremost, throw the hitch several inches nearer the draft than otherwise could be done, at the same time gainiu g strength by the position of the timbers.

F represents a'plow-beam with clevis attached.

By reference to Fig. 5 it will be seen that the clip G is held from dropping down by coming in contact with the lower part of the clevis; yet from the position of the bolt which attaches it to the clevis it is allowed to rise when occasion requires, and by this construction the double-tree or triple tree is always held in a horizontal position and never allowed to fall about the horses heels.

When it is desired to make of the apparatus a double-tree only, the middle single-tree, D, and clip K are removed, together with the eveners,.and the end single-trees are placed in the clips J J and the clips shifted on the doubletree strips to the right spot to make a doubletree for two horses.

t will be seen that there are no vertical holes in any of the timbers, and instead of a holein thecenter of the double-tree, as usual, the plate H extends out from the center and supports the strips away from the center, and greatly shortens the breaking leverage, as will be seen in Figs. 1, 2, and 3, as represented by the dotted lines.

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is-- 1. The double-tree strips A and eveners B B, in combination with the plate H and clips J J, the clips and plate being held in place by means of lateral wood-screws, substantially as set forth.

2. The double-tree strips and single-trees placed arch side foremost, incombination with the eveners and clips J J and LL, said clips being: held in position by meansof lateral screws, substantially as shown and described.

3. In combination with thedouble-tree strips and evencrs, the clips K K and single-tree D, substantially as shown and described.

4. The plate H-, provided with the hole S, recesses P P, and tongue V, substantially as set forth. 7

5. The single-trees G E and eveners B B, connected by means of the clips L L, and held in position by means of lateral screws, substantially as set forth.

6. The double-tree strips A A and singletrees placed arch side foremost, in combination with the eveners and clips L L K and J J, the clips being held in place by meansoflateral screws, substantially as set forth.

7. Incombination with the double-treestrips,

eveners, and singletrees, the clips J J L L, plate H, and clip G, substantially as set forth. 8. In combination with the double-tree strips, eveners, and single-trees, the clips J J L L K, held in position by means of lateral screws, substantially as set forth.

9. In combination with the double-tree strips A, eveners B B, and single trees 0 D E, the clips J J L L K, plate 11, and clip G, substau tially as shown and described.

10. The ends of the eveners, rounded, as shown at 0, Fig. 6, for the purpose of making a rear bearing for the clips L L, in combination with lateral screws, substantially as shown and described.

11. The combination and arrangement of the plate H, provided with the tongue V, and the clip G, whereby the double-tree strips are held and prevented from springing inward or outward, substantially as set forth.

12. The clip K K, held onto the single-tree by means of a lateral screw, and having rearwardly-projeeting arms, to which the eveuers are attached, substantially as shown and described.

13. In combination with the double-tree strips A A, the movable or adjustable clips J J, held in place when adjusted by means of lateral screws J, whereby the double-tree may be converted into a triple'tree, substantially as set forth.
